Final answer:
Firmware is installed in read-only memory in devices and provides low-level control for the device's hardware. Unlike application software, firmware is typically read-only but can be updated by the manufacturer.
Step-by-step explanation:
The firmware is installed in special, read-only memory in devices like printers or communication devices. Firmware is a specific class of computer software that provides the low-level control for the device's specific hardware. It can be thought of as the software that directly interacts with the hardware components.
Firmware exists on various devices, including printers, routers, cameras, and also embedded systems.
Unlike application software, which can be installed and modified by the end-user, firmware is typically read-only but can be updated with newer versions by the manufacturer to fix bugs or add features.
